[edit] typeid

Language built-in operator. Queries information about a type or expression and returns type_info object corresponding to the type.

See typeid operator.

[edit] type_info

The class type_info describes type information of a type, generated by the implementation. This is the class, returned by the typeid operator.

[edit] type_index

The class type_index is a wrapper around a type_info object, that can be used as index in associative and unordered associative containers.

[edit] bad_typeid

The class bad_typeid is the type of the object that is thrown if the argument in a typeid expression is null.

[edit] bad_cast

The class bad_cast is the type of the object that is thrown by an invalid dynamic_cast expression. The standard explicitly defines it will be thrown when a cast to a reference type fails.
